Arsenic Advances

Arsenic and its compounds have been known to be toxic for millennia. Arsenic trioxide (As2O3), often referred to as white arsenic, was a favored poison in the Middle Ages because it had little odor or taste, enabling it to be easily incorporated into the food or drink of a victim. As little as 300 mg can be fatal to an average person.
